A commercially available transfer printing process is depicted in Figs. 1A through 1C. The process, generally known as the "Tampo" process, involves impressing a soft, conical-shaped transfer pad of specially formulated silicon rubber or similar material against an inked master plate having the image to be transferred. The ink is picked up on the surface of the conical transfer pad, as shown in Figs. 1A and 1B, where the transfer pad 2 is lowered by mechanism 3 to contact the printing plate 1. In Fig. 1B the transfer pad 2 has been fully depressed to contact the printing plate 1. In Fig. 1C the transfer pad has been moved by mechanism 3 to a position above an article 4 to be marked and depressed to transfer the ink from the pad 2 to the article.
